On Board Diagnosis Logic

UBS00D5O

This self-diagnosis has the one trip detection logic.
This diagnosis checks whether the engine coolant temperature is extraordinary high, even when the load is
not heavy.

CAUTION:

When a malfunction is indicated, be sure to replace the coolant. Refer to 

MA-16

 , “Changing Engine

Coolant”. Also, replace the engine oil. Refer to 

MA-20

 , “Changing Engine Oil”.

1.

 Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to 

MA-14, "ANTI-FREEZE COOLANT MIXTURE

RATIO"

 .

2.

After refilling coolant, run engine to ensure that no water-flow noise is emitted.

Overall Function Check

UBS00D5P

Use this procedure to check the overall function of the coolant over temperature enrichment protection check,
a DTC might not be confirmed.

WARNING:

Never remove the radiator cap when the engine is hot. Serious burns could be caused by high-pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap by turning it a quarter turn to allow built-
up pressure to escape. Then turn the cap all the way off.

1.

Check the coolant level and mixture ratio (using coolant tester) in the reservoir tank and radiator.
Allow engine to cool before checking coolant level and mixture ratio. 

If the coolant level in the reservoir and/or radiator is below the proper range, go to 

EC-249, "Diagnostic

Procedure"

 .

If the coolant mixture ratio is out of the range of 45 to 55%, replace the coolant in the following proce-
dure 

MA-16

 , “Changing Engine Coolant”.

a.

Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute like pouring coolant
from a kettle. Be sure to use coolant with the proper mixture ratio. Refer to 

MA-14, "ANTI-FREEZE COOL-

ANT MIXTURE RATIO"

 .

b.

After refilling coolant, run engine to ensure that no water-flow noise is emitted.

c.

After checking or replacing coolant, go to step 3 below.

2.

Ask the customer if engine coolant has been added. If it has been added, go to 

EC-249, "Diagnostic Pro-

cedure"

 . After repair, go to the next step.

3.

Start engine and let it idle.

4.

 Make sure that A/C switch is “OFF” and air conditioner is not operating. If NG, check air conditioner cir-
cuit. Refer to 

MTC-22, "TROUBLE DIAGNOSIS"

 . After repair, go to the next step.

DTC No.

5.

Start engine and make sure that cooling fan operates.
Be careful not to overheat engine.
If NG, check cooling fan. Refer to 

CO-16, "COOLING FAN (CRANKSHAFT DRIVEN)"

 . After repair, go to

the next step.

6.

Check for blocked coolant passage.

a.

Warm up engine to normal operating temperature, then grasp radiator upper hose and lower hose and
make sure that coolant flows.
If NG, go to 

EC-249, "Diagnostic Procedure"

 . After repair, go to the next step.

Be extremely careful not to touch any moving or adjacent parts.

7.

Check for blocked radiator air passage.

a.

When aftermarket fog lamps have been installed, check for damaged fans and clogging in the condenser
and radiator. 

b.

Check the front end for clogging caused by insects or debris.

c.

Check for improper fitting of front-end cover, damaged radiator grille or bumper, damaged vehicle front.
If NG, take appropriate action and then go to the next step.

8.

Check function of ECT sensor.
Refer to 

EC-251, "Component Inspection"

 .

If NG, replace ECT sensor and go to the next step.

9.

Check ignition timing. Refer to 

EC-74, "Basic Inspection"

 .

Make sure that ignition timing is 20

°±2° at idle.

If NG, adjust ignition timing and then recheck.

Diagnostic Procedure

CAUTION:

Higher than the specified pressure may cause radiator damage.
Pressure should not drop.

CHECK MAIN 11 CAUSES

If the cause cannot be isolated, go to 

EC-250, "Main 11 Causes of Overheating"

 .

>> INSPECTION END

Perform FINAL CHECK by the following procedure after repair is completed.

1.

Warm up engine. Run the vehicle for at least 20 minutes. Pay attention to engine coolant temperature
gauge on the instrument panel. If the reading shows an abnormally high temperature, another part may be
malfunctioning.

2.

Stop vehicle and let engine idle. Check the intake and exhaust systems for leaks by listening for noise or
visually inspecting the components.

3.

Allow engine to cool and visually check for oil and coolant leaks. Then, perform “Overall Function Check”.
